It will be noted that the plate 11. fits into the recess formed by the offset wall '10 of the body portion, the lower flange of the body portion resting on the upper face of the flange 3, and the flange of the body portion extending into the channel 12, In this manner a vertical brace'for the entire rail structure is provided,
